DIRECTION INDlCATOR.

Patented Jan. 25, 1921.

wvemz a device for mounting on auto vehicles mnncnon-mmcnron.

To'all whom z't mag concern: Be it known that LAWRnNon Pxs'ronn, acitizen of the United States of Amer1ca', re-. sidin at Newark in thecounty of Lickmg and tate of Ohio, has invented new and useful Imrovements in Direction; Indicators, of whic the following is aspecification.

The object of the invention 15 d a jacent to wind-shield whereby thedriver of a particular vehicle may indicate to those in his rear andalso to those in front n cluding the traflic ofiicer the dlrection hentends taking. To this end the 1nvent1on comprises a. casing 'forosltionlng transversely across the vehicle ehlnd or in front of thewind-shield. Th1s casing carrles a signal element lonfifudinally movabletherein so that it may caused to project from one end or the other ofsaid caslng for the purpose of effecting the signal. in operation.

' its movement is efiected by means of a hendle and geared connectionsbetween the handle and said element whereby the movement of the handlemay cause the said element to beextended from one end or the other ofthe casing for the useful purpose above prises stated. o

. To the exact construction in which it is shown and described,theinvention is not to be restricted. The applicant reserves the right tomake such changes or alterations as the actual reduction to'practice maysuggest, in so far as such changes or alterations are compatible inspirit with the annexed claim. The same numerals of reference designatethe same parts throughout the several figur es of the drawing, herein: yV Figure l is a view lookmg at the front dash and wind-shield of an autovehicle, the improved deviceshown mounted thereon and appearing in sideelevation.

As'shown'the invention is desig1 ed pref-- 1 of an auto vehicle which asis usual is provided with a wind-shield 2: The indicator comreferablysquare in cross section and which I 1s o en at either end.

connected to it the brackets 5 by means of wh1ch the whole is attachedto the dash 1. In the rear or on that side facing the driver of theveh1c1e,the casing 3 and its dependent sectlon are closed by theremovable element 8 is of slightly less length than the casing 3 so thatboth it and the lights which proyect from both ends may be inclosedentirely within the casing except when the said element is projectedfrom one end or the other of said casing. The signaling element 8 is fhollow constructionand its top wall is formed with a longitudinal slot10., this slot forming a clearing space for contact members 11- as thesignaling element is Irgoved longitudinally through the cas- 1n nthe'bottomface of the bottom wall the signaling element is provided witha plurality of rack-teeth 12 and these rackteeth mesh with a gear 13carried on a pintle 14in common with a pinion 15. This intle or shaft 14is journaled inthe forwar wall of the depending section 4 and in thatpart of the cover 6 which closes the said depend- Meshing with. thepinion 15 on a shaft 17 which is rotatably mounted in both the cover 6and the forward wall of the depending section 4. The shaft 17 alsocarries a pinion l8 and. this latter is in mesh with a gear 19 mountedon a spindle or shaft 20, the latter bein journaled as are theshafts 1'?and 1t. he shaft 20 is the gear 19 for the'rocking of the latter whole.is effected by means of a handle 21 projecting through and movable fromone extremity to another of an arcuate slot 22 formed in that partof thecovert which closes the dependmovement of the handle Ql-to the righthandend of the slot 22 will result, because of the connections justdescribed, in a longitudinal movement of the'sig'naling element 8longitudinally a right-hand direction through the casing 3, the gearratio being such that when the handle 21 abuts the right-hand end of theslot 22, the end of the signaling ele ment will be projected from theright-hand nawmcn 1. was, on nnwimx, cam.

end of the casing 3. Similarly the movement of the handle 21 to theleft-hand end the signaling element, it is the purpose to illuminate thesignal lights 9 when the signaling element is extended its proper dis- 7tance and to this end the contact members 11 are provided, these beingsecured to the upper wall of "the casing 3 by approprlate fasteningmeans 23 and being insulated from said upper wall by appropriateinsulation 2 the fasteners also being insulated from the upper wall asindicated at 25. It will be observed that there are two contact elements11 both of which are spaced a definite distance to either side ofthelongitudinal center of the casing 3 but these two contact members areelectrically connected by a wire or rod '26 to which there, is ledthrough the top of the casing a conducting wire 27. This conducting wire27 connects with one terminal of the battery '28 whose upper terminal isconnected with the easing 3 or some metallic part of the structure ofthe device by means of a conducting wire 29., o

Cooperating with these contact members 11 there is a contact member 30.This is carried within the signaling element 8 and is mounted on thebottom wall of the latter, being insulated therefrom by the strip 31.@ne terminal of each light 9 is electrically connected to the contactmember by the wire 32, the other terminal of each light being connectedwith the metallic body of the 'slgnaling element b means of the wire 33.

As the signaling cement is moved longitudinally through the casing 3,the contact 30 connects with either one or the other of the contactmembers 11 when the signaling element reaches its extreme projectingpoescapee s'i'tion.- "In such a position therefore the rived fromth'e'battery 28, this current passing from the-battery over the wire 29-to the aling element '8,

casing 3, thence to the si ence through the thence over the wire 33, tlamp filament, thence over the wire 32 to the contact 30, thence to thecontact 11 and thence over the wires 26 and 27 back to the battery. Ofcourse when the signaling element is positioned so that it standsentirelywithin the casing 3, the contact 30 stands between the twocontacts 11 with neither of which it connects, and the circuit on thebattery is therefore broken at this point with the result that bothlights are deprived of current.

From the foregoing description and the accompanying drawing, it isbelieved that a clear enough understanding of the invention is to be hadto render further descriptlon unnecessary.- V g The invention havingbeen described what is claimed new and useful is A direction indicatorcomprising a long hollow casing for mounting on an auto vehicle with itslength in the direction of the width of the vehicle, the saidcasingbeing.

open at its ends formed with'a central depending hollow section, asignaling element slidably mounted insaid casing and carry ingsignalingmeans at its ends, the outer face of the bottom wall of saidsignaling elementbeing formed with rack teeth, a rock shaft mounted insaid depending section, a gear carried by said rock shaft, a handlecarried by said gear and projecting through an arcuate slot formed insaid section, and intermediate gears connecting the first said gear withthe said rack teeth, whereby the movement of said handle from one end ofthe said slot to the other will efiect the longitudinal movement of thesignaling element for the useful purpose specified.
